Specification of Letters Patent.

Patented Got. 14.2, 1915.

Application filed August 20, 1913. Serial No. 785,659.

I To all whom it may concern:

Be it known that I, JOHN J. FARRAR, a citizen of the United States, and a resident of Rapid City, in the county of Pennington and State of South Dakota, have invented a new and Improved Container, of which the following is a full, clear, and

. exact description.

My invention relates to a manner of packaging cement, lime, plaster and other loose materials that aresubject to hard usage in handling and transportation.

The invention includes a novel container for the materials, an improved method of charging the container, and a novel package formed by means of the container.

The container is adapted to be filled with the cement or like material, and is composed of telescoping sections whereby after receiving the material, the sections are telescoped together to compact the material into the form of a self-sustaining body for which the container forms a cover or envelop, the sections of the container being united to each other after the compactingof the material, to hold the latter in a substantially solid form. The ends of the container are formed ina novel manner to constitute end closures.

The invention will be more particularly explained in the specific description following. v t

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of ref.- erence indicate corresponding parts in, all the views.

Figure 1 is a vertical section of a package of loose material enveloped by my improved container; Fig. 2 is aperspective view thereof; Fig. 3 is a longitudinal sectional view showing the container ready for filling; Fig. e is a fragmentary perspective view of one end portion of a tubular section of the container before forming the ends; Fig. 5 is an end view of a section partly finished; Fig. 6 is a vertical sectional elevation showing a modified form of the container; Fig.

7 is a view similar to Fig. 6, but illustrating a further modification; Fig. 8 is a view similar to Fig. 4, but showing amodified form of the end of a tubular section; Fig. 9 is an end view of a tubular section showing the end closure produced by the form shown .in Fig. 8; and Figs. 10 and ll are end views showing further modifications of the end closure.

In carrying out my invention in accordance with the form of the container illustrated in Figs. 1 to 5, two tubular sections 10, 11, are provided, the one being of a size to snugly telescope within the other, the sections being approximately of equal length.-

Each section is formed with longitudinal slits 12, thereby producing a series of tongues 13. The slits may be parallel, as shown in Fig. i, andan equal distance apart, andsuflicient in number to produce pairs of tongues, the tongues of a pair being diametrically opposite each other. The tongues also may be of a length so that when folded inward over the end, opposite tongues will abut at the center of the end, as shown in Fig. 5, and the tongues may be folded in such succession that alternate tongues will overlap each other, providing a form of in-.

terlock.

In whatever order the tongues be folded, I provide on the interior of the end a covering 14 of cheese cloth, paper, or other suitable sheet material which is secured to the inner faces of the tongues by a suitable adhesive material. Similarly on the exterior of the folded tongues I apply a 'covering 15 of suitable sheet material, and secure the same by an adhesive.

In practice, the tongues are bent over a curved or approximately dome-shaped formation, the ends merging into adjacent side portions of the container on rounding lines. Also the slits 12 are out to such a depth that the inward curving of the ends will' start outward from the inner ends of the slit, and thus not have a marked tendency to bend sharply or crack in being turned inward.

The one tubular section is formed with a lateral inlet opening 16 between the ends thereof, through which the material is entered laterally into the container after the one section has been fitted to the other, as shown in Fig. 3. The ends of the section's when the container is to becharged are separated a sufiicient distance to locatethe inlet opening 16 beyond the inner end of the other section. A quantity of the material is entered into the container sufficient to more than fill one section and the sections are then telescoped on each other until the inlet in the one section is closed by the other the material (indicated by the numeral 17 A in Fig. 2) within the container into a practically-solid body, which will be substantially self-sustaining and require that the container be only of suflicient strength to form a reasonably strong envelop, the result being that the complete package may be handled after the manner of a stick of wood.

It is to. be observed that when the sections have been collapsed to a degree to thoroughly compact the material, the sections are united to each other, which may be done by applying any adhesive'material to the outer surface of the inner section at a point to be overlappe by the outer section when the container is collapsed to the fullest extent.

The rounded end portions iii-practice, not only serve to avoid sharp angles on the package, but serve to crowd the material toward the center at the end portions of the container, so that the material at the ends of the package will be compacted as fully as at other portions throughout the length of the package, and indeed will be packed to a greater degree at the rounding portion,

- whereby the ends of the package, which will be subjected to perhaps greater ill usage, will maintain their form.

In the form shown in Fig. 6, a plain unslitted cylinder20 is produced, and on each end thereof is a telescoping section 21, in

- the form of a cap, it being understood that the-outer end of each telescoping cap is formed with tongues 13 similar to the tongues 13, the tongues being secured by inner and outer coverings 14B, 15 as in the first described construction. With this form of container the package may be formed by removing oneend cap and filling the cylindrical body 10 and the opposite cap 21, after which the remaining cap is placed in position, there being a quantity of material projecting above the body for the material to be solidly compacted by forcing home the cap under pressure.

In the form shown in is formed at one end with integral tongues 13', which are secured by an mner covermg material 141: and an outer covering material 15 The opposite end of the container is closed by a telescoping cap 21, the end of which is formed by tongues 13, having an inner covering 14 and an outer covering 15, which may be similar tothe coverings 14 15. The form of container shown in Fig. 7 is filled in the same manner as that illustrated in Fig. 6.

In Figs. 8 and 9 I have shown pointed tongues 13 which will all fold toward the central point as indicated in Fig. 9.

Fig. 7, the m 20,

aware? In Fig. 10 the tongues 13 are formed of such a length that thetongues of opposite pairs will-overlap each other.

In Fig. 11 the tongues are formed the same as in Figs. 1 to 5, but are so folded that opposite pairs will abut each other throughout their end portions, and successive pairs are merely folded, without overlappingedgewise, as on the tongues of other pairs as in the arrangement shown in Fig.' 5.

- The outer container in all instances desirable has a vent-hole 22 near the top which will be closed by the inner section.

The container in practice, is made of sizes to contain standard quantities, such as are now put up in ordinary sacks, bags, half barrels, etc., and my improved package possesses the advantage, of being more conven- -made of light cardboard or paper, which may be formed by successive layers or coils one on top of another, after the manner of known forms or cardboard mailing tubes, etc.

The improved package also lends itself to handling by machinery, which is not possible with ordinary cement bags.-

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v I
